Hello folks,I have a m6600 laptop with i7-2760qm, 8gb ram and a firepro m8900 gfx. I'm looking for a good gfx upgrade for better gaming performance (especially fallout 4). I've locked down on two candidates: FIrepro M6100 and Quadro k4000m. Here's the ebay links for both. The seller assured me that the cards will be compatible with my laptop.M6100: http://www.ebay.ca/itm/Dell-Precisi...252699?hash=item4d46335b9b:g:-VoAAOSw3YNXbT6XK4000M: http://www.ebay.ca/itm/HP-Dell-M660...512594?hash=item25c38bdad2:g:uzYAAOSwi0RX0AnAI would like to hear some great advices from all you pros, especially if you have hands on experience on either cards in your m6600 lappy:1. I wonder if m6100 would be an easier option for my lappy since it's AMD product like my m89002. I wonder if I go k4000m do I need to change my x-bracket, rearrange thermal pads or even need to change the heatsink (sorry I haven't changed a laptop gfx before)I'm in favor of k4000m since it has twice the video memory, more ROPs and TMUs which is great for gaming. M6100 may run a bit cooler and has more OC potential (it has 1050mhz gpu base clock vs 600 for K4000M). All in all, I'm choosing between an underclocked GTX 660 and a HD 7790, though I could bring the K4000M clock up a bit. But Nvidia cards are more optimized for gaming. What's your thought folks?
Of course if you have better options especially if there's anyone has upgraded to gaming cards like GTX 680M, HD 7970M or 760M, 765M, 675M, etc I'm eager to hear from you folks.Thanks for your inputs!

During normal wildstar gameplay my CPU and both GPU's reach 90+ degrees C. This seems abnormally hot to me. Does anyone else have these hot temperatures? Will disabling hyperthreading have a significant effect in cooling down my cpu during load?

Well, after my ZBook died because of faulty bios (hardware related) and it had a K4100M (OC) with HP vBios,
i wanted it to be on my old 8770w, but it just gave me no screen output (laptop screen) only on VGA (didn't test on DP cuz i got no DP Monitor nor cable) and i liked how the K4100M had better performance than the K4000M (Well the oc made the bandwidth go from the original 102 GB/s, to 200 GB/s [Not stable at all in some games like Rust, or Heavy iray rendering] vs the K4000M 89 GB/s [BTW I couldn't find any SAFE way to oc it]
So I decided to make some research and testing,,
Long ago before I started searching on how to do this change of gpu i found out that people had 980m in their 8770w and also k5100m without any errors, just by modifying the drivers, i tried so and failed. This is my laptop Specs:
HP EliteBook 8770w
Quadro K4000M
Intel i7 3820mq
2x500GB WD Blue (Only ones i had around empty in my inventory)
20GB of ram (I know its not "correct" but i used 3x4GB and 1x8GB RAM sticks)
1080p Screen Non-Dreamcolor
Windows 10 Pro 64 Bits - Creators Update (Btw im in Insider Program) Notes:
This laptop has no Optimus support as far as i know,
I havent tested on more vbios, only on 1 OC Dell Vbios
I didnt test video output on DP, Beacuse i have no DP Monitor nor a cable, and i dont need it, at all.
The laptop didnt give any video on integrated screen, only on vga with OC HP vbios and aswell Original (Backed up) vbios, only with the Dell vbios made successful output to laptop screen.
There was video going on at VGA without nvidia drivers, if i installed the drivers the screen had artifacts like random colors then the laptop freezes and shutdowns with errors, even with dell vbios.
GPU temp was higher than usual, even when it wasn't on high load.
I was able to run Besiege at 5 fps without a driver (Only with Microsoft Display adapter). So by some hours of testing this were the results:
I replaced the K4000M with the K4100M,
I used windows recovery thing at startup (since the nVidia drivers from K4000M bugged the hell out the screen output) then I selected the CMD option, did cd to the folder where i had nvflash, flashed my gpu from there, with a OCed DELL vbios, (link), and then restarted my laptop,
I was so excited because i made it make video output through the laptop screen, and then i loaded windows normally and the drivers started to bug the screen and then windows crashed after 4m every time i logged to windows (even without logging in), it said Video tcp failure (or something) and Watchdog_DPC_violation,
So i used a fresh windows install (from a HDD i had around), it did give 1080p video output to laptop screen and i didnt test anything at all, so then installed Normal Nvidia drivers (from nvidia not hp neither dell) and then it started to bug again,
And well, Then i tried using Ubuntu (17) and the screen give 1080p output without problems, i was going to install nvidia drivers but it was too difficult for the short time i had to test, so i didn't finished up testing with Ubuntu,
As some dude told me at other forums that it might be an Optimus driver bug or something, so later on ill try testing with modified drivers.
Also the GPU temp was high, i didn't check out the temp, but the laptop was too hot for normal use and used too much battery life (i found out when i was playing around with Ubuntu at my couch).
And months before, I found out that in Nvidia page it said that the K4100M worked only on Haswell Generation (4th gen), and not Ivy Bridge,
now it says that supports Shark Bay, which is kinda new, since that "option" wasn't there before.
This is what ill do next time i make another test:
I'll use another vbios a not OC one, just a normal one,
Modify nVidia Drivers to try removing optimus (if posible)
Finish testing up in Ubuntu
Try to use older Drivers to see if anything happens.
Post the pics of the Artifacts and a video of besiege running with Default video Driver

Hello!
I am a new to techinferno - what brought me here is an issue with a Precision M6700 I bought myself lately. The laptop came with no GPU in it, however I have a GTX 880m that fits it's MXM slot. When I plugged the card in I though it was all I needed to do - I'm used to desktop upgrades, so I thought - it fits - why not? Turns out the PC's BIOS can't figure out what card is in it - with Optimus "off" I can see "unknown video card" with 8GBs of RAM. Windows 10 x64 Anniversary Edition works and recognizes the GPU as "Microsoft Universal Video Adapter", but the HWid suggests it's a GTX880 - in fact I can even see it properly detected by GPU-Z.
So I browsed through lots of topics on upgrading, modding and customizing drivers but none of the methods worked for me, apart from one - Mr Fox's modded desktop drivers. I managed to install all the nVidia components, yet can't get the card working properly - launched Bioshock Infinite to see if it is on and it wasn't. Apparently my M6700 wants to perform only on Intel HD graphics from the CPU (3940XM). I tried flashing different vbios, updated the Dell bios to the latest one (A15), and tried modding NV drivers - no luck so far. Installing drivers (DSE turned off obviously) sometimes gives a post "no compatible hardware was found" and at other times with different mods and versions I get a message that it was all recognized, yet the driver "migh have been corrupted or smth"...
I still believe that it is possible to make it work if it's only a software issue. Question is - how deep do you have to get into modding to make it work? Is the GTX 880m even worth the effort? Maybe I should search for a way to mess with M6700 BIOS? You might wonder why I want it - the answer is simple - I don't want a Quadro card here as I see a potential for some gaming on the workstation which has excellent build quality and great computing power.
That's when I come to you asking for help - I've seen people upgrading their laptops with the impossible, so I believe there's still hope.
Other useful info: I have a spare Quadro K5100 to try out, but from what I've read, there might be issues with that one as well...
edit
If anyone reads the thread - I was succesful with the upgrade - everything installed and working. I wish it was more stable, but still it runs great. If you need any tips, just PM me

Hi guys! I just recently got a used m15x (with a gt240m gpu...) and have swapped it out for a gtx880m (msi) which is not working currently. I have updated the bios to a09, and then installed the unlocked a09 bios to unlock all options to make sure something there wasn't to blame.
The laptop boots and gets to windows just fine if you're plugged into a monitor via VGA, but windows does not recognize the gpu or let you install drivers for the card. Additionally, if a monitor is not plugged in the laptop screen goes white and emits one very loud beep every few minutes. Aside from this, the laptop behaves as expected. I'm having trouble finding any support online regarding this issue and was hoping that somebody here could give me a bit of a pointer on where I should look to next.
as a side note, forgot to add that I originally purchased the card after finding a list of people showing off benchmark scores for different cards in the m15x, one of which was the 880m, which could be purchased cheaply online. I'm currently looking into how to flash vBIOS as it was mentioned in one of the few posts I could find on the subject, but am waiting to hear if this is the right course of action. thanks in advance for any assistance you can provide!

Hello Everyone.
This is my first post, I'm not really that well educated in the world of laptops, so please go easy, I might need a bit of hand holding here.
my laptop is the GT70-0nc, its the barebones MS-1762 I believe, I bought it from a custom laptop builder online. The 675m is fried I think, BSOD all over the place, disabling it and switching to my HD4000 integrated fixed the BSOD.
I'm looking into upgrading the GPU of my laptop except there's some things that have me completely baffled...
1. Which GPU's are actually compatible? - I was looking at the 680m but if there are newer gpu's that work I'd love consider those too.
2. I have read a lot about flashing my BIOS, this really confused me. I get the American Megatrends Logo on boot up, so I tried checking out their BIOS but everything i've read says use the MSI VBios?
I have a good bit of experience with the hardware in my laptop, I've taken it apart quite a few times like to change thermal paste / general maintinence and upgrade my WIFI card. it's the software and compatibility issues that are really getting me stuck.
Any help would be massively appreciated!
Thanks

Listed on eBay here: http://www.ebay.co.uk/itm/AKiTiO-Thunder2-PCIe-Box-Thunderbolt-to-PCIe-e-g-Mac-eGPU-/201808361125
For sale is one boxed AKiTiO Thunder2 PCIe Box. This has been modified - as per various tutorials available online - to open up the back panel which otherwise restricts the length of PCIe card it can hold. This - plus a suitable power supply - enables this device to support full size/length GPUs. (The supplied power unit is sufficient to power the Thunder2 box itself plus any PCIe card with standard power draw, such as Ethernet Adaptors, Fire Channel cards, SAS/SAT, Firewire/USB, Storage, etc. Some lower-power GPUs do not require any additional power but most do, which is why the suggested solution for an external GPU is to use a PC PSU. For that reason, this auction includes the molex-to-barrel connector that I used to power my eGPU, though lots of other solutions are available. Enjoy experimenting!)
If you're reading this listing then you probably already know what you're doing but if not - or if you get stuck - the Tech|Inferno Forums (among others) are a fantastic source of information and that's where I learnt how to set mine up: https://www.techinferno.com/index.php?/forums/forum/83-diy-e-gpu-projects/
I had great success with this, using it to add an NVIDIA GTX 970 GPU to my 2011 Mac mini which made it a gaming powerhouse. I'm selling this now because I've finally sold my beloved Mac mini for something newer. An eGPU can be used in macOS and Windows.
If you have any questions about this particular unit please get in touch before buying or making an offer. I will be very happy to respond!
Please note:
No GPU is included in this auction. You can use any PCIe card. The photos here including a GPU are for illustrative purposes only. The external case, fan and power supply are all included. The case and power supply have never been used, since my large graphics card would not fit inside the closed case as it arrived and I used an external power supply. But if you want to use this with a smaller card, you can certainly fold the side back in and use the outer case, fan and power supply as designed if you wish - it's all included. NB: I didn't keep the little power LED at the back of the case but be assured it's not needed and there is an LED on the board anyway that shows when it's powered.
The box says the product is not compatible with Apple's Boot Camp and does not support graphics cards. There is nothing technically stopping it (and it works great) but due to a clause in the licensing of Thunderbolt technology they are not officially allowed to market it as such.
This sale is aimed at gamers/enthusiasts. It definitely works brilliantly but is neither supported by me nor by the manufacturers so I can't accept a return on the basis you couldn't get your eGPU to work right. There is a lot of information online and some fantastically helpful people in various forums. Also, it's not at all difficult and extremely satisfying - so have a go! If you want to use this device as per its original intention, the official product page is here: https://www.akitio.com/expansion/thunder2-pcie-box

Hi guys!
I have a big problem-> I need to undervolt my GPU (MSI 7970M@DELL_BIOS).
I am using this vBIOS: https://www.techpowerup.com/vgabios/132831/dell-hd7970m-2048-120629
Stock VDDC on this GPU is 1.050V and when I changing this one to 0.975 in VBE7 it is ok-> I can save it and flash it. Computer succesfully restarts but when I check modded settings the VDDC is still on 1.050V
I checked if the VBE7 seriously saving the VDDC to vBIOS but it is ok. I have no idead what i need to UV this card (i know it's possible...)
Everything is changing (GPU, MEM MHz) but VDDC can't change.
Please help me ;-)

Hey guys,
I am pretty new here. This is my first post (I posted a similar thing on Reddit). I have been a long time lurker and am keen to get your guys' input on what I have to offer.
So I found the Akitio Node for sale from this UK company:
http://www.equip-u.com/shop/index.php?main_page=product_info&cPath=45_896&products_id=20752
Seems like a legit site from what I can tell etc. And it's even linked on the Akitio official website 'Where to Buy' page for Europe (https://www.akitio.com/where-to-buy/akitio-sites). But there's nothing on their site about being in stock etc.
Now I've been lurking for a while and it looks like none of the Thunderbolt 3 eGPU boxes(apart from the Razer Core) are actually available at all in Europe yet. Am I missing anything?
TL;DR version: Is it worth ordering from these guys on the chance that they actually have it in stock?

Hello, I bought a Zotac GTX660 Synergy and the card ONLY works on my Asus Workstation (C600 Chipset / 850W / Old UEFI).
I tried an old LGA775 520Watt non UEFI, a recent MSI B150 Chipset UEFI and on my EGpu system without success.
The card is simply not recognized, the MB bios gui doesn't start at all, black screen.
If I start the system with internal GPU the Zotac doesn't appear anywhere.
Any ideas?
Thank you.

Hello,
i recently bought a x7200 with one gtx 680m in it. now im planning to upgrade to sli with an other gtx680m.
but i can't find a heatsink with fan.
so the question is: does the p570wm GPU heatsink fit into the x7200? they look very similar. or does someone sell parts of a x7200?
thanks in advance

Hey tech inferno,
I started my eGPU/docking station project a little while ago, using a cooler master elite 120 white as the enclosure, an akitio board, a gtx 970, and a 1tb samsung ssd (for external windows 10). Everything is powered by a 650 watt evga power supply, and the akitio is connected with a soldiered barrel plug to a chopped molex cable. The first time I tested it with a 750ti (before buying a 970) everything just worked. I pugged the thunderbolt in while windows was booted, and installed the latest drivers. The screen flickered, and that was it. Done. Everything worked. Optimus worked flawlessly, external monitor worked flawlessly, frame rates were amazing (for a macbook) and my computer itself stayed cool. I immediately returned my friend's 750ti and bought a 970. Once I got around to installing it I was at college, but it was the same as before. Once I got the computer to recognize the card (in device manager), I installed the drivers, the screen flickered, and everything worked, just faster. I had a blast playing some games that I had been missing while working on the project. For several days I was able to either connect the egpu by plugging it in while the computer was off, turning on the power supply, waiting 15 seconds, and then booting, holding alt, and booting onto my external ssd; or just booting into windows and then hotplugging my egpu. It always worked, and it was better than I ever expected. Then, one day, I came back after class, and nothing worked. No hotplugging, no successful boots, and no accelerated video. Once in a while I could get it to boot, but when it did that it was only because it didnt recognize the card at all, and just used iris pro. Can someone help me get my setup working again? My laptop is the 2015 macbook pro 15" (for which there are few guides). I'm hoping someone else has overcome this problem. I have tried reinstalling drivers, but it no longer freezes the screen and works, it instead requires me to restart, and when I do, it breaks. Major karma to anyone who helps me out. I can put pictures (or video of boot failures) if someone wants me to.
thanks!

You know, I really hate myself, I do. I swore to myself this time, "don't fall for NVIDIAs shit, you can resist the temptation of Titan X". So I held out, bought a 1080 thinking "ok I got this!". What helped even more was it was constantly out of stock on their website. So tonight I just check it for shits and giggles and what do you know, it's in stock. My finger starts twitching and I'm thinking, "oh fuck no you aren't!" and the next thing I know, I'm at the checkout process w/next day shipping. God damn you NVIDIA! I know in a few months I'll look back on this post and think, "damn I'm an idiot" but what the hell.
Update a day later (today):
It arrived this afternoon and it's definitely an impressive card. My biggest gripe is I have to set the fan to 90% when its boosting to 2 ghz in order to keep it from going above 80c. Since I game with headphones on, that's not a big deal for me. In overwatch with the gtx 1080 @ 2.05 ghz and 1440p max settings I wasn't able to get above 90-95 fps. This card stays in the 130-144 fps range which is perfect for my display.

hello, I have a problem and I need help, I have a clevo p170em with a radeon HD 7970M card, the card burned and I ended up getting another one gtx 485m. however this board was to an earlier model to my windows and does not accept the driver of it. I wonder if posivel make any changes in the bios or if you have any nvidia driver for this card that works in clevo p170em.I am desperate because I need the card to work and do not have to buy another one now.

Hello ive seen a few people asking about heat and i thought i would chime in and say a few ways to keep down the heat!
there are a few ways you go about this with out opening the computer, for those who arent to sure about taking a screwdriver to their laptop it may help you.
in saying that, if your fans are dirty then this will not help you at all.
I TAKE NO RESPOSIBILITY TO ANY DAMAGE HARDWARE! ANY CHANGES YOU MAKE ARE AT YOUR OWN RISK!
INCREASING THE FAN SPEED
to control your fans use this
http://www.hwinfo.com/download64.html
this is a free program that alot of people use on various computers. it work on alienwares well but im yet to test ROG and MSI with it.
its pretty simple to use
install it and get to this page and click on the sensors button
then on the next screen click the small fan icon at the bottom
unless you want to manually adjust your fan between each time you play click customer auto and you can edit it from there
UNDERCLOCKING
download and install NV tools it can manage fan speeds too but its not always 100% in laptops
http://www.nvidia.com/object/nvidia-system-tools-6.08-driver.html
on the left hand side, under the performance tab, select device settings
now just slide it back in small steps until you are comfortable with the temps. remember that if your computer blue screens it DOES NOT mean your computer has been damaged. it is simply a way for the computer to avoid damage.
adjust the slider in intervals of about 15mhz to be safe and click apply each time.
start on the core clock and finish on the memory. Every now and again it is good to check on your progress to see how far you need to go. (more on this later)
MSI after burner is a good one too
http://www.guru3d.com/files-details/msi-afterburner-beta-download.html
again the fan control is a bit hit and miss with it but it can control your clock speed. ass per the program above keep going untill you hit a STABLE setting you want.
TESTING
here we will look at the new GPU temps after the tune.
MSI Kombustor is a great way to test your heat.
http://www.geeks3d.com/20150710/msi-kombustor-v3-5-2-64-bit-v2-6-0-32-bit-download-gpu-stress-test-benchmark/
click on stability and watch the temps. if you see any artefacts stop the test and increase the mhz by 15mhz each
fur mark is the one that i use to test the heat of my alienware
http://www.ozone3d.net/benchmarks/fur/
aim for about 70-75*C.
hope this helps you a bit.
PS avoid EVGA's tuning tool on alienware i have heard it can brick your LCD!
CLEANING THE FANS
Just for the sake of it ill give you a few tips on cleaning your laptops fans out.
assuming you already know the basics of using a screwdriver to open a laptop ill cover a few things to help you.
REMEMBER, IF YOU REMOVE THE HEATSINK YOU WILL NEED NEW THERMAL PASTE!
compressed air is a great way to remove dust and id recommend having a can of it over a compressor. The reason being is that some compressors can fill with a bit of water and can spray it directly into the computer.
you can spray the air into the vents and while it wont really "clean" it it may open enough room for air to pass out. i DO NOT recomend this however.
after opening up the computer and removing the fan take a paint brush and clean the entire fan, get as much of the dust out as you physically can.
you can use toothbrushes too if you dont have anything else.
make sure you clean the grill behind the fan too as that is where the dust usually builds up.
removing this dust and hair is the most important part of this clean up.
now on to thermal paste.
remove all the old thermal paste from the heat sink and the CPU with a dry cloth then, use isopropyl alcohol to clean the rest.
some people seem to think that more is better but this is completely not true! if you put a large amount of thermal paste on the heatsink you will actuall have hotter temps.
this is due to either:
A ) the heatsink is not geting enough connectivity to the GPU as the layer of thermal paste is too thick
B ) too much of it creates small pockets of air, these air pockets become super hot and that causes more heat on the GPU
the correct amount is roughly the size of a pea
even that is boarderline too much.
Dont spread it around instead place your heat sink over it as even as possible and screw it down in a X pattern for an even spread.
really hope this helps you and good luck!

Hi, I would like to share my eGPU experience with EXP GDC V8 ExpressCard on my W520, Quad core i7, 12GB RAM, Quadro 2000M 2GB dedicated VRAM, Windows 10 Pro 64bit.
last month after weeks of fails and errors, (specially the famous Error 43), i finally got my EXP GDC running using mPCIE version with NVIDIA Quadro 4000 for Mac (yes, for Mac!)
I make it works by setting the PTD switch to 7s. But by the time Windows successfully detect my Q4000 i straught away hook up my external monitor (EIZO CG245W 24-inch) to my eGPU, then the system blinks, i assume it detect a display signal. but it wasnt. And my W520 suddenly shutdown. And i can not make it work again. Even after hundreds of time reinstall-uninstall NVIDIA Drivers with DDU it wont make it work again.
So, at this point i switch the GPU to my Quadro 6000 6GB GDDR5, and repeat the last success process. Nothing happened. Our good friend Error 43 back again and stay there forever.
In my desperate time, i finally ordered the ExpressCard signal Cable.
While waiting it's enroute somewhere in China, I test the EXP GDC with my AJA Kona 3G 4K I/O Video Capture Card, and hey it's working! i can do Edit & Realtime Preview 4K RAW video files thru the card flawlessly, It utilized the card's hardware encoding, (4K RAW files from ARRI & RED Camera) as well as output 16-Channels 192KHz Audio signal from my DAW. (no additional 6-pin power required for this card)
Then i test my both Quadro 4000 & Quadro 6000 GPU back to my HP Z800 workstation, guess what? They're both bricked! It received power, but system cannot boot up. Beeping. means GPU is faulty.
The next day, my AJA Kona 3G card also bricked!
Today the ExpressCard signal cable finally arrived along with my 6-pin + 6+2 pin, but again, when i use the ExpressCard setup it doesnt do anything. No power comes in to the EXP GDC. My 500W ATX PSU is running though, but the LED indicator on the EXP GDC not lit. i set the slot to Generation 1 power mode in BIOS.
So, I've tried both mPCIe and ExpressCard on W520 with nothing but frustrations. Did i miss anything here?
I appreciate any workaround on this. Since i've never found any eGPU setup with W520 anywhere in the net. specially using ExpressCard & a High end Quadro GPU.
Here's my last config that i've managed to make Q4000 work:
mPCIe method:
BIOS:
Whitelist latest BIOS 1.42
Power Management: Both for Processor and PCI set to Disabled
Display Mode: Integrated Graphic
OS Detection Mode for Optimus Graphic: Disabled
PXE Boot and all Network Boot options including PCI LAN Boot order : Disabled
Win 10:
Device Manager: System Detect eGPU, Error 43
Uninstall NVIDIA Driver with DDU (safe mode)
Reboot
Check BIOS first, usually it will set back the Display to Optimus Mode, i Let it Boot in OPTIMUS MODE

[IMPORTANT NOTE]:
You will know your graphic card is working fine when you power on your laptop, normally all Quadro cards fan spin at normal speed, then it will spin faster/accelerate for 3-4 sec at Windows logo, means the system & OS detects your card then it back to normal fan speed.
During the setup, i often get my Quadro 4000 fan spin so freakin fast. Faster then the POST boot init, but then back to normal speed
Bricked Quadro Graphic Card: Quadro 4000 Fan spin fast forever, while Quadro 6000 stays low speed.
Thanks a lot!

NVIDIA's Pascal is on it's way and should be available sometime in June based on current leaks. One of the first GPUs may be a full GDDR5x GP104 based GeForce 1080 GPU and we will almost assuredly have mobile variants shortly thereafter. AMD hasn't given us nearly as much information on Polaris except their performance/watt demo a few months ago but we're fairly certain it is priming for release as well.
With the new generation of GPUs quickly approaching, do you plan to upgrade to either of them upon release? Why or why not?
